Which of the following regarding species interactions is INCORRECT? a) The net effects of a mutualism on each participant is a fixed characteristic of the interaction, and is rarely influenced by external factors. b) Reciprocal parasitism is an accurate way of describing many mutualistic interactions. c) The Lotka-Volterra competition model accounts for the effects of both interspecific and intraspecific competition.
Competitive exclusion occurs under the following conditions: a. when fundamental niches overlap and competition is asymmetric b. when realized niches overlap and competition is asymmetric c. when fundamental niches overlap and competition is symmetric d. when realized niches overlap and competition is symmetric e. when competition is excluded because niches do not overlap
Which of the following statements is correct regarding the competitive exclusion concept? a. multiple species can’t share the exact same niche within a community b. the realized niche of a species is different from its fundamental niche. c. competition within a population results in the success of the best-adapted individuals. d. two species cannot coexist within the same habitat.
Which of the following can explain why species are able to coexist, even if the competitive exclusion principle is generally true? a) Species may be competitively equivalent, with the outcome of each competitive encounter being essentially random. b) Competitive exclusion may take many generations; prior to that point, there will be coexistence. c) Spatial heterogeneity in the distribution and concentrations of limiting resources can result in variation in the strength of competition across the landscape. choose all the answers that apply.
Briefly explain 3 adaptive responses that an organism might show to minimize the negative effects of competition. These responses might be regulatory, evolutionary, or anything else that is ecologically relevant.
According to the competitive exclusion principle,a. one species is always more competitive than another for a particular food source.b. competition excludes multiple species from using the same food source.c. no two species can occupy the same niche at the same time.d. competition limits the reproductive capacity of species.
Which statement about zero population growth isoclines of two competing species is true? A. Species coexistence requires that the two isoclines cross. B. The crossing of the two isoclines is a sufficient condition for species coexistence. C. If the species coexist, they will each do so at a higher density than either would if placed alone. D. Strongly competing species can only coexist if the two species have very different carrying capacities. E. Coexistence will occur if the two isoclines are parallel.
As the density of a population of crickets increases, the abundance of their food (plants) decreases, and there is a corresponding decrease in the population growth rates of crickets. As adult crickets forage they are observed chirping (vocalization) and share the best feeding locations. This interaction is an example of … a. interspecific interference competition b. intraspecific exploitative competition c. interspecific exploitation competition d. intraspecific interference competition
7)Which of the following is the best definition of a trophic cascade? a)Significantly changing the population size of one species causes significant changes in the population dynamics of other species b)Adding or removing one species causes significant changes the population dynamics of other species in the community c)Significantly changing the population size of a species at one trophic level causes significant changes in the population dynamics of populations that do not directly interact with this species d)Adding or removing species causes a collapse of the food web for that community e)None of these definitions are accurate
1. From the animals in the figure, which species could have a positive indirect effect on the Possum? 2. If you suspect that competition between Wallabies and Bandicoots is leading to coexistence, describe an example of a piece of evidence that would support your idea. 3. If Tasmanian devils become extinct in the wild due to DFTD, name a species other than cats that you expect would change in abundance as a result. Explain how you think that species' abundance would change and why.
